Ubiquitous and pervasive computing is fundamentally
transforming product categories such as music, movies, and books
and the associated practices of product searching, ordering, and
buying. This paper contributes to theory and practice of digital
payments by conducting a design science inquiry into the mobile
phone wallet (m-wallet). Four different user groups, including
young teenagers, young adults, mothers and businessmen, have
been involved in the process of identifying, developing and
evaluating functional and design properties of m-wallets.
Interviews and formative usability evaluations provided data for
the construction of a conceptual model in the form of sketches
followed by a functional model in the form of low-fidelity mockups.
During the design phases, knowledge was gained on what
properties the users would like the m-wallet to embody. The
identified properties have been clustered as ‘Functional
properties’ and ‘Design properties’, which are theoretical
contributions to the on-going research on m-wallets. One of the
findings from our design science inquiry into m-wallets is that
everyday life contexts require that evaluation criteria have to be
expanded beyond “functionality, completeness, consistency,
accuracy, performance, reliability, usability, fit with the
organization, and other relevant quality attributes” [12] that are
used within current design science work.

This paper uses three meditations to contemplate walking, sensing and participation as three ways with which we can extend the notion of ‘experiential computing’ proposed by Yoo (2010). By using the form of meditations, loosely associated concepts that are part introspective and part ‘causative’, i.e. aimed as some form of change in perspective within Information Systems Research, the paper weaves empirical incidents from fieldwork with theoretical concepts on movement, sensuality, and embodiment, suggesting directions for methodologies and techniques to be pursued if experiential computing is intended to also inform the design of technologies for the future. By emphasizing the senses and the body and their importance to an extended notion of sensory apprenticeship (Pink, 2009), the paper suggests alternative routes to knowing and representation in IS related fieldwork.
